well, it may sell a few hundred copies worldwide, similar to Sony RX1R/II models. there simply is no market - not even a niche to speak of - for fixed prime lens digital cameras costing north of 4k.
photo enthusiast scientists ... well, zeiss might offer them a ZX1 as "free gift" when ordering hi-end gear for the lab. but no, that might be not in compliance, so Zeiss won't do it and even when, scientists would never accept, right? so, back to a few dozen units sold to collectors and their glass cupboards.
other than that, zeiss ZX1 is way too big and too heavy for what it is: FF sensor with bolted-on, single focal length 35mm/2.0 lens. Can be had in a truly compact package as well.

ZX1 is a Frankenstein combo of Android mobile gadget - with Adobe Lightroom slapped on top to make things worse - and outdated analog camera days UI concept with 2 mono-functional dials for Tv, ISO and aperture ring. a bit reminiscent of failed UI approach on Nikon Df. No buttons for AE-Lock or AF-L for back-button AF that any serious user would want!? Touchscreen plus fewer dials and buttons makes all sense in the world, but only if implemented "really right". On ZX1 is it "really limiting".
Nice big hi-rez big display, but why not articulated and why 16:9 yuck!, when sensor is still 3:2 ... another of the video-induced compromises that impair stills shooting functionality and user experience.
512GB internal memory, fine. but why not add a UHS II or even better UHS III (Micro) SD slot in addition? For expandability, redundancy and fast transfer whenever wireless options are not available? Body is large enough to fit even dual SD slots, right? And Price will undoubtedly be high enough to cover a few extra bucks for a SD chip and slot, no?
communication - why stop halfway? Only WIFI? If Android, then why not give it built-in LTE/4G chip to eliminate need for a separate smartphone when camera is along.
And if body is that large, why not give it a 24-70/4.0 zoom lens at least, or even better: an interchangable lens mount! eg new L-mount, if it really is "open standard". That would nicely upset Leica and be great fun.
Overall: typical half-assed "concept car" approach: all glitz, all show, nothing road-worthy.
